You can take a pregnancy test as early as about 6 to 10 days after conception, when the hormone human chorionic gonadotropin (hCG) starts to be produced and can be detected in urine or blood. However, for more accurate results, it is generally recommended to wait until the first day of your missed period or about 11 days after your missed period for standard home pregnancy tests

. Some highly sensitive early detection tests can detect pregnancy up to 6 days before your missed period, but testing too early may result in a false negative because hCG levels might still be too low to detect

. For best accuracy:

• Test with the first morning urine when hCG concentration is highest, especially if testing before a missed period

• Avoid drinking excessive fluids before testing to prevent diluting urine

• If you get a negative result but still suspect pregnancy, wait a few days and test again

• Blood tests at a doctor’s office can detect pregnancy earlier and measure exact hCG levels

In summary, the ideal time to take a pregnancy test is from the first day of your missed period, using first morning urine for best accuracy. Early tests can be taken a few days before your missed period but may be less reliable
